MQTT, OPC UA and the IIoT — Frequently Asked Questions
All of our Windows based IPCs and Touch Panel PCs can run WinCC Runtime Advanced as well as WinCC Unified. Using our IPCs running WinCC, you’ll generally get a higher performance device per dollar with a more ruggedized enclosure with higher screen resolution, more RAM and SSD options, and the ability to run other industrial software on the same machine with more advanced remote access tools.
You can use our Windows or Linux based IPCs and Touch Panel PCs to run Ignition Edge locally. You can also use our HMIs to communicate with Ignition via Modbus TCP, OPC UA, and MQTT, which makes a programmers life easier when building distributed edge gateways, dashboards, or data collection nodes within an Ignition-powered architecture.
